21.57 is what percent of 32.36 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 32.36 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 32.36, so we can write it down as 100%=32.36.
4. We know, that x% equals 21.57 of the output value, so we can write it down as x%=21.57.
5. Now we have two simple equations:
1) 100%=32.36
2) x%=21.57
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=32.36/21.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.57 is what percent of 32.36

100%/x%=32.36/21.57
(100/x)*x=(32.36/21.57)*x       - we multiply both sides of the equation by x
100=1.5002318034307*x       - we divide both sides of the equation by (1.5002318034307) to get x
100/1.5002318034307=x
66.656365883807=x
x=66.656365883807

now we have:
21.57 is 66.656365883807% of 32.36
